Chrome extension page update listener html5

[KalleCro]

Code:

window.addEventListener('yt-page-data-updated' || *spotify page data updated*, function () {
    console.log("url changed")
    setTimeout(function(){
        if(!document.getElementById("play-extension-ytbtn") || !document.getElementById("play-extension-btn")) {
            fnAddButtons();
            fnDefineEvents();
        }
    }, 1500);
});

I need the equvivalent of the youtube listener (yt-page-data-updated) just in spotify. I didn't found anything. Thanks in advanced!
